19 Claims. (01. 101-365) The invention relates to new and useful improvements in ink supplying mechanisms for printing presses; and more particularly to such improvements in the ink fountain, fountain roller and associated parts of rotary printing presses.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, ormay be learned by practice with the invention, the same being realized and 1 attained by means of the instrumentalitiesand combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown. and described.

15, The accompanying drawings, referred toherein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

40 Objects of the invention are to provide an ink fountain mechanism whichis of simple and sturdy construction, accurate and reliable in. operation, and which may be easily and quickly cleaned. To this end, and in accordance with certain features 45 of the invention, a fountain roller is .iournaled in permanent position on the press frame and preferably directly in the side, frames of the press and a support for the fountain knife blade is also carried by the press frame, and the fountain it- 50 self, preferably of light sheet material, is itself bodily insertable and removable, and may be quickly and easily removed and replaced, without disturbing the fountain roller or knife. Other features and advantages of the invention will be 5:; pointed out in the following'detailed description,

and it will be understood that the foregoing general, description and the following detailed description as well are illustrative and exemplary but are not restrictive of the'invention.

Referring now in detail to the embodiment of 5 the invention illustrated by way of example in the accompanying drawings, the fountain roller is journaled in the vertical side frames of the press, and as embodied (Figs. 1, 2 and 3) the fountain roller 1 has its projecting shaft ends 2 10 and 3 journaled each in a pair of spaced apart collars 4 and 5 fitting within and at either end of a cylindrical sleeve or bushing 6. The bushings 6 'are fitted in corresponding cylindrical openings in the vertical side frames '1 and 8 of the press. The outer ends of the bushings 6 are formed into flat flanges I I, which abut on the exterior faces of bosses formed on the outside of the vertical frame members I and 8. The bushings are held firmly in position by tap bolts 12 which pass through the flanges, and are threaded into the side frames. .The inner ends of the bushings 6 fit to the abutting flat ends 'of the fountain roller i.

In accordance with certain features of the invention, theink fountain itself is separately removable from and insertable into operating position with reference to. the fountain roller. The ink fountain is preferably of sheet metal or other light construction, and as embodied comprises a body portion 18, having flaring, and somewhat inclined, front and rear walls It and 20 and a forwardly and downwardly inclined bottom 2|, and flat inwardly and downwardly inclined ends 22 and 23. The end walls 22 and 23 have cutout portions 24 of a width substantially equal to the diameter of the bushing 6, the lower part of the openings being on substantially the radius of the bushing, so that the end walls will fit snugly to the bushing when the fountain is in position about the roller.

The means for holding the fountain firmly and accurately in position while permitting its quick removal and reinsertion comprise (Figs. 1, 2, 3 and 4) a pair of rigid plates 21 (Figs. 1, 2, 4 and 8), which are of beveled vertical cross section, decreasing in thickness from the top downwardly on the side toward the corresponding end wall of the fountain, and are located within and their inclined sides abut against the inside faces of the 60 vertical ends 22 and 23, respectively, of the ink fountain. Plates 21' extend entirely across the ends of the ink fountain and have their front and rear edges abutting against the front and rear walls 2! and ll of the ink fountain. The

plates have circular apertures 28 therein, which fit snugly about the bushings 6, which extend inwardly through the recesses or openings 24 in the end walls 22 and 23 of the fountain and fit against the fiat end of the fountain roll I, as shown in Figs. 2 and 3. Set screws 29 are threaded into apertures 30 in the tops of the plates 21 and enter and press against key-ways 35 in the bushings 6, and hold the plates 21 firmly to the bushing, and against the insides of the vertical ends 22 and 23 of the fountain, in proper assembled position. Loose on the threaded part of each bushing 6, respectively, and on the exterior of the side walls 22 and 23, respectively, of the fountain is a cylindrical spacing and holding washer 33, which is tapered in vertical cross section increasingly from the top to the bottom on one side with the same inclination as the member 21 and" the adjacent end wall of the fountain,

but in thereverse direction. This washer can slide freely'along the bushing, but is held from rotation by a key or spline 34, working in a keyway 35, extending longitudinally in the threaded part of the bushing B. Cooperating with the foregoing is a nut 38 threaded on the bushing 6 exteriorly to the spacing and holding washer 33.

Means are provided for temporarily positioning and supporting the ink fountain preparatory to permanently fastening it in operative position by means of the mechanism just described, and as embodied, there is formed on the outside of each of the end walls 22 and 23 of the fountain a vertically-disposed bar 40, and each of these bars has a pin 4| projecting outwardly from the upper part thereof. Formed on the under side of the fountain plate support 41, later to be described in detail, is a lug 42 from which is pivotally suspended a latch lever 43, having a notch or recess 44 formed therein. The various parts of the permanent fastening means for the fountain are in approximately the position of Fig. 3 when the fountain is returned to position and is lifted upwardly past the position shown in Fig. 3 to that shown in Fig. 4. The levers 43 are then moved clockwise and the recesses or hooks 44 engage beneath the pins 4|, as shown in Fig. 4, at which time the straight top edges of the end plates of the fountain fit snugly beneath the fountain knife support 41, thereby accurately positioning the fountain. To firmly fasten the fountain in position, the spacing washers 33 are moved against the outside of the corresponding end walls 22 and 23 of the fountain, and the nuts 33 are screwed up tight, when the parts are in the position shown in Fig. 2, the end plates of the fountain are clamped between the members 21 and 33, and the fountain is held firmly in position, and the openings in the end walls are sealed by the plates 21, and the fountain may be run as full of ink as may be desired without leakage occurring about the fountain shaft.

In accordance with one feature of the invention, the fountain knife supporting means are mounted on the machine frame, and as shown a horizontal plate 41 extends across the press, and has-upwardly extending bracket plates 48 and 49 at either end, the outer surfaces of these plates fitting against the inner faces of the side frames, and the plates are fastened to the side frames by tap bolts 50 which pass therethrough and are screw-threaded into the frames. Beneath the horizontally-extending plate 41 is a supporting plate 53, and the fountain knife 54 is mounted between these plates and screw-bolts 55 pass through plate :53 and are screw-threaded into the bar 41 to hold the parts firmly in position. Formed across the front side of bar 4], and extending forwardly and upwardly therefrom, is the inclined bar 56 through which are screw-threaded a plurality of adjusting screws 51, the points of which bear upon the knife 54 and adjust the pressure of the knife upon the fountain roller I.
